Key Inflation Data and Drivers
- The Australian Bureau of Statistics reported annual CPI at 4.6 % in the 12 months to March, up from 3.7 % in February – the highest level since September 2023.
- Monthly CPI rose 1.1 % in March, led by a 9.2 % increase in transport costs and a 32.8 % jump in automotive fuel prices. Housing inflation contributed 6.5 % to the annual rate, while electricity prices rose 25.4 % after rebates expired.
- The trimmed-mean measure of underlying inflation held steady at 3.3 % year-on-year, still above the Reserve Bank of Australia’s (RBA) 2-3 % target band.
RBA’s Policy Outlook and Official Statements
- The RBA warned that “Developments in the Middle East remain highly uncertain, but under a wide range of possible scenarios could add to global and domestic inflation.” Board minutes described inflation as “still too high” and highlighted “the rise in oil prices” as a risk of prolonged overshoot.
- Governor Michelle Bullock said the board agreed that rates “may need to rise further” and that “higher fuel costs will not slow demand enough on their own to address this.”
- Treasurer Jim Chalmers framed the situation as “largely a story about international pressures playing out at the bowser.” The RBA’s preferred trimmed-mean figure remained unchanged at 3.3 %, reinforcing the view that underlying price pressures persist.
Market Reaction and Economic Impact
- The S&P/ASX 200 slipped 0.2 % to 8,691, extending a seven-day losing streak. The Australian dollar fell to 71.7 US cents, while three-year government bond yields eased to 4.70 %.
- Energy stocks rose as Brent crude hovered near US$111 per barrel; financials showed mixed performance, with Commonwealth Bank down 1.3 % and ANZ up 0.4 % after announcing a purchase of its payments JV partner Worldline.
- Analysts priced a 76 % probability of an RBA rate hike at the upcoming meeting, down from 85 % earlier in the week.
Criticism, Opposition, and Divergent Views
- Some economists argue for a pause. Tony Sycamore (IG) cited a “counterargument for the RBA to keep rates on hold in May” given recent declines in petrol prices. Adam Boyton (ANZ) warned that “an attempt to engineer a rapid return of inflation to target would come at quite a considerable cost to the labour market.”
- Public commentary echoed concerns that “borrowers are penalised for high inflation that stems from a war, not domestic demand,” and questioned whether “higher fuel costs have the same effect as higher interest rates.”
Conflicting Reports & Gaps
- Reuters reported annual CPI at 4.1 % and trimmed-mean core inflation of 3.5 %, while ABS data placed CPI at 4.6 % and trimmed-mean at 3.3 %.
- Market odds for a third consecutive rate rise varied between 76 % and 85 % across sources.
- The data captured only the “initial impact” of the Iran-related oil shock; subsequent quarters may show larger effects, but precise forecasts remain absent.

What’s Next
